Chris’ e34 extravaganza

[jc43089]

You need to put oil in the cylinders and recheck.  I have seen dry cylinder walls cause extremely low compression.  I had a flooded M50 show 30PSI on compression test and with a little oil it jumped back to 180.  It also wouldn't start because compression was so low.  I just cranked it over with the plugs out and injectors unhooked to dry the fuel away and added a squirt of oil to each cylinder and it started right up.  That was on my e36 a couple months ago when it was extremely cold out and had a failed start attempt.

This.

I had a two stroke inline 6 that had numbers roughly all over the board; 60,50,110,80,130. I was super worried. Added oil, rechecked compression and it was 160's all the way across. I was shocked.

Bingo.  Rebuild that S38 and make something that will make @DrLeadFoot feel bad about his S62 touring.

Here you go. find a perfect box for that S38 diamond like this one and make a nice faux M5.

Sorry I haven't updated in awhile, very busy with school and weather is just finally getting nice where I wanna be in my garage

I appreciate all the suggestions from everyone, I'm going to put some oil in the cylinders and re-run the compression test. I also visited home this past week and grabbed my borescope so I can check out the cylinder walls and pistons.

I can easily hook up pressurized air to the hose that came with my compression tester kit so I'll do that also if the compression numbers are still low

For now I've been pulling the car apart, I had a moment today in the garage as I was gutting it (easily lost 400lbs today) thinking how cool it would be to rebuild it, completely simplify the car, cage it, put some light bucket seats in it and use it, until the carpet came up and the skirts came off 

I had a lot of fun getting this skirt off. A PO jacked on the fender seam and bent the fender/skirt up into the body of the car with the bolt holding the skirt on smashed inwards. When all this shit fell out after the skirt came off I knew it was no good

Yeah its bad up front. Extending beyond this hole towards the frame rails under the undercoating is completely soft. The metal has rusted away just leaving a sheet of just undercoating haha

Can see the hole to the front right of the jack point, although it looks mostly intact it's made up of multiple layers of metal and they are all swollen with rust in-between the layers.

Rear wheel well, same story as the floor pan, completely rusted through under the undercoating up about a solid 6in beyond what you can see

random firewall rust holes on the passenger side

Hard to tell but this is a hole into the rockers

Same story but worse on the passenger side

Mysterious rusty puncture hole in the battery area

Yeah so I've played this game before and I'm not going to again. I'm sure the inside of the rockers is horrifying

Funny thing is though, parts of this car are really rust free, the rear jack points, pan and rockers dont even have surface rust. No rust on the quarters, no rust on the rear trunk lip, fenders aren't rusted through. This was a texas car until 2002, The rust is probably from sitting uncared for in a wet environment with trapped water for 11 years and not salt. Shame

Making progress

Idk what I'm doing with everything, I want the shell gone and all the regular e34 parts gone. I'm just kinda gonna hang on to everything M5 specific for now

It sucks doing this to this car, it really does. I feel bad every time my garage opens and you see such a special car with nothing but a M5 badge left on the rear.

sad the shell isnt a keeper!

I’m guessing that the door bottoms are torched after seeing all that rust?

The front doors might actually be rust free I’ll check them out, one of the rear doors has a massive dent

Sad day. Yeah that thing is pretty gone. I feel your pain. Its crazy how much damage can happen from moisture. 

At least you won't lose money with the parts from it.

Curious to see the new compression numbers.

[Rekpoint]

I wonder if you can retrofit the ITBs to fit on an S52.

Yeah let me know, the fronts on mine started showing a tiny bit of rust hidden under the door trim this last winter. Also might be interested in the driver rear window regulator and motor. 

@Rekpoint the bore spacing is different so they wouldn’t line up perfectly without some sort of adapter, and they’re likely too big for that motor anyways. You’re probably better off buying an ITB kit specifically for the s52.

It was worth the chance,
